Brief Summary

To investigate the safety, tolerability, efficacy and pharmacokinetics of TCR-T cells in the treatment of advanced pancreatic cancer

Conditions

Pancreatic Cancer

Keywords

TCR-T; T cells; RAS; TP53; Cell therapy

Outcome Measures

Primary Outcomes (2)

• Evaluate the Incidence of Treatment Related Adverse Events of TCRT cells in patients with advanced pancreatic cancer

  collect adverse events (AE), serious adverse events (SAE), adverse events of special interest (AESI), and laboratory abnormalities (type, frequency, and severity)

  2years

• Characterize the Peak of Peripheral Blood Concentration and Area under the Peripheral Blood concentration versus time curve of TCRT cells and observe their proliferation and persistence in body

  After infusion of neoantigen-specific TCRT cells, collect peak (Cmax) of neoantigen-specific TCRT cells in blood and tumor tissue, time to peak (number of days to peakTCRT cells after infusion), Tmax) and AUC0-28 (area under the curve plotted against visit time by the number of neoantigen-specific TCRT cells in peripheral blood from day 0 to 28). "If possible, AUC0-inf, terminal phase elimination rate constant (λz), elimination half-life (t1/2) will be evaluated."

  2years

Secondary Outcomes (2)

• Correlation of the pharmacokinetic profile of TCRT cells with the Incidence of CRS and ICANS events

  2years

• Evaluate tumor size (mm) , tumor biomarker CA19-9 (U/ml), ORR/DCR/PFS and OS of patients with advanced pancreatic cancer

  2years

Other Outcomes (1)

• To explore the correlation between the proliferation and persistence of TCRT cells in body and the efficacy

  2years

Study Arms (1)

TCR-T Cells Injection（GB3010 Cells Injection）

EXPERIMENTAL

This study was designed to evaluate the safety, tolerability, efficacy, and pharmacokinetics of TCRT cell injection (GB3010) in patients with advanced pancreatic cancer by intravenous injection. The target population is patients with advanced pancreatic cancer who lack effective treatment methods, so that the benefits of patients participating in clinical trials will outweigh the risks.

Drug: TCR-T Cells Injection（GB3010 Cells Injection）

Interventions

TCR-T Cells Injection（GB3010 Cells Injection） DRUG

The TCRT cells used in this clinical trial were derived from the patient's autologous peripheral-blood T cells and were genetically transduced to express a T-cell Receptor that recognizes the RAS/TP53.Patients were sequentially enrolled into 3 dose escalation groups(dose level 1-3) :5×10\^8±20%,5×10\^9±20%,5×10\^10±20%.
